Abstract

fetched live from OpenAlex

Cette thèse combine une double approche géomorphologique et sédimentologique associée à l’utilisation de données LiDAR, bathymétriques, photogrammétrie drone et de datations radiocarbones. Elle a permis de reconstituer les paléos dynamiques glaciaires en contexte de déglaciation pour l’Inlandsis Laurentidien depuis le dernier maximum glaciaire, il y a environ 20 000 ans, et plus précisément au passage d’une marge glaciaire ancrée en mer à une marge glaciaire continentale Deux études ont été menées conjointement, soit : (1) la cartographie, la synthèse et la proposition d’un modèle concernant les mégacannelures de la Côte-Nord du Saint-Laurent, une première pour ces morphologies et (2) la reconstruction de l’enregistrement géomorphologique et morphosédimentaire du complexe sédimentaire de Pentecôte, mimant précisément cette transition. D’une manière générale, cette thèse démontre l’importance de l’héritage structural et de la physiographie du plancher au marge glaciaire dans la reconstruction de la dynamique glaciaire de retrait de la marge du LIS oriental.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
